I have implemented phone sign-in OTP validation. So, when I enter the phone number, it checks against the list of phone numbers that i have in firestore database. (or i have to use difft database for only phone number that are allowed to login.
I think i am using wrong database of firebase. cause i want already present phone numbers.
If i use FIRESTORE DATATABSE - but what happen when i login from number/otp. it create new document id with new data of login. where no phone number is present. cause it create DATA only when you login. please help me to solve this query Inactive Member @Adrià Solé
